Used as a key intermediate in the synthesis of agricultural chemicals, particularly herbicides and plant growth regulators. Its structure allows for the development of compounds that selectively inhibit weed growth in crop fields, especially in rice and wheat cultivation. It is also utilized in the preparation of pyrimidine-based pharmaceuticals due to its reactive chlorine sites and carboxylic acid functionality, enabling coupling reactions in drug development. Its stability and reactivity make it valuable in research laboratories for designing new bioactive molecules.
